I've been having an intermittent problem with code P1004 (short runner valve). At 53k miles i got a code for it and immediately purchased the part and had it changed. Light never came back for about 4k miles Then after i started tuning my car light started to resurface every now and then. I'd say it comes on about every 1-200 miles of driving or sometimes won't come on at all. Anybody have experience with this, Do you think the part could have gone bad again? or is it something deeper. Thanks (14 srt charger) Can anybody please get me the part number for the piece i cannot find anything for it on google thanks.
